* see "MADI IO-Modules" on page 30


Chapter 1: Overview

ApplicationsEXBOX.BLDS can be used as a plain signal switch or for sophisticated observation of MADI signals with automated switch-over and revert.Typical applications include:

• Signal distribution• Playback applications, e.g. live performances• Observing MADI transmission with external reporting

How it worksOne of the two MADI input signals is routed to both MADI outputs. Depending on the settings the input selection is triggered manually (by a push button or by a GPI contact) or automatically (by a trigger condition).Trigger conditions are:

• loss of carrier (no input lock)• loss of BLDS signal• loss of Audio Pilote Tone

The inputs can be prioritized for revert when the signal is regained after a loss. Additionally the selection of an input may by forced by a GPI contact.External control is offered by four GPIs and the output signal state is monitored by four LEDs and four GPOs.


Chapter 1: Overview

The BLDS signal for enhanced signal observation is generated by a BLDS Generator and inserted into the MADI stream by a DAW. The artifical design of the control signal enables detection of signal loss or corruption. An automated and inaudible switch-over is executed within one sample.

Audio Pilote Tone means the presence of an audio signal with a level > - 42 dBFS in channel 56 @ 1 FS (28 @ 2 FS). Trigger after downtime > 10 ms.

Input StateTwo LEDs each inform about the signal state of both MADI inputs. For detection of the BLDS signal MADI channels 8, 16, 24, 32, 40, 48, 56, 64 are observed.

BLDS 1 LED (green) indicates the presence of a BLDS signal at MADI input 1.LED OFF = no BLDS signal detectedLED ON = BLDS signal detectedLED heartbeat = watchdog active*

BLDS 2 LED (green) indicates the presence of a BLDS signal at MADI input 2.LED OFF = no BLDS signal detectedLED ON = BLDS signal detectedLED heartbeat = watchdog active*

* See „Watchdog“ on page 45.



SYNC 1 LED (green) indicates the lock / sync state at MADI input 1.LED OFF = no signal or no lock or not in sync with internal referenceLED ON = signal is in sync with internal reference

SYNC 2 LED (green) indicates the lock / sync state at MADI input 2.LED OFF = no signal or no lock or not in sync with internal referenceLED ON = signal is in sync with internal reference

NOTE

The synchronization of the BLDS signal takes a few seconds. During this period the BLDS LEDs are flashing.



Input SelectionThe blue push button on the left side is be used to select the input signal manually. Depending on the priority setting the input is selected automatically - see „Priority Setting“ on page 40.Three GPIs may be used to select or to force an input - see „Control via GPI“ on page 44.

INPUT SELECT Push button to select the MADI input.Press to alter the selection.






Output StateTwo LEDs each monitor the selection of the MADI input for the two MADI outputs (SYNC) and the presence of a BLDS signal at the output (BLDS).

BLDS 1 LED (yellow) indicates the presence of a BLDS signal (MADI input 1) in the output signal.LED OFF = no BLDS signal present or MADI input 1 is not selected for the outputLED ON = BLDS signal is present and MADI input 1 is selected for the outputLED heartbeat = watchdog active*

BLDS 2 LED (yellow) indicates the presence of a BLDS signal (MADI input 2) in the output signal.LED OFF = no BLDS signal present or MADI input 2 is not selected for the outputLED ON = BLDS signal is present and MADI input 2 is selected for the outputLED heartbeat = watchdog active*



SYNC 1 LED (yellow) indicates the selection of MADI input 1 for the output signal.LED OFF = MADI input 1 is not selected for the output.LED blinking = MADI input 1 is selected for the output but no valid signal is detected.LED ON = MADI input 1 is selected for the output.

SYNC 2 LED (yellow) indicates the selection of MADI input 2 for the output signal.LED OFF = MADI input 2 is not selected for the output.LED blinking = MADI input 2 is selected for the output but no valid signal is detected.LED ON = MADI input 2 is selected for the output.

* See „Watchdog“ on page 45.

The activation state of each port and the presence of the BLDS signal is also monitored by four GPOs - see „Monitoring via GPO“ on page 48.



Priority SettingDifferent characteristics of the MADI switch allow to adapt varying scenarios. It ranges from manual input selection to automated switching with prioritized inputs with watchdog control or detection of either BLDS or Audio Pilote Tone. Depending on the priority setting the input can be selected manually.The priority setting is adjusted by the blue push button on the right side or alternatively by a GPI - see „Control via GPI“ on page 44.

LED Code CharacteristicInput Selection

manual switching yes

Priority condition: lock on input #1 – revert to #1, when lock is regained

no

Priority condition: lock on input #2 – revert to #2, when lock is regained

no




No priority – standard redundancy > switchover at signal loss, no revert when signal is regained.

yes, if both inputs are locked

Priority condition: BLDS and lock on input #1 – revert to #1, when BLDS is regained.

no

Priority condition: BLDS and lock on input #2 – revert to #2, when BLDS is regained.

no

No priority – standard redundancy requiring BLDS at both inputs – switchover at loss of BLDS, no revert

yes, if both inputs detect BLDS




Watchdog activePriority conditions: - lock on input #1 - state change at GPI #1> switchover at loss and revert to #1 when both conditions are complied with.

no

no

Priority condition: Audio Pilote Tone and lock on input #1 – revert to #1, when Audio Pilote Tone is regained.

no

Priority condition: Audio Pilote Tone and lock on input #2 – revert to #2, when Audio Pilote Tone is regained.

no




No priority – standard redundancy requiring Audio Pilote Tone at both inputs – switchover at loss of Audio Pilote Tone for longer than 10 ms, no revert

yes, if both inputs detect Audio Pilote Tone

CharacteristicsThree switching modes are possible:

• manual switch• automated switch without revert• automated switch with revert

Automated switching follows to one or two of the defined conditions:

• input signal lock• BLDS present• Audio Pilote Tone present• watchdog at GPI

See „Watchdog“ on page 45.

Audio Pilote Tone• any audio signal with a level > - 42 dBFS• present in channel 56 @ 1 FS (ch 28 @ 2 FS)• trigger at loss > 10 ms• revert immediately at detection



Control via GPIFour GPIs offer full control of the device via remote or external equipment.Each GPI can be triggered by connecting the input pin with ground (GND) or by a voltage source between input pin and ground. The high level of the voltage may range between 2 V and 24 V due to a safety limiter in the input.

* See „DSUB-9 (female) - GPI“ on page 61 for wiring details.



WatchdogA state change on GPI 1 (or 2) is needed to maintain the adjusted priority setting to the prioritized input.The minimum alternation frequency of the GPI state amounts to less than 0.5 Hz (i.e. every two seconds).

• GPI 1 is used for watchdog on input 1.• GPI 2 is used for watchdog on input 2.

Active watchdog is indicated by blinking codes of the LEDs in all three sections.Example:

Input Priority set to input 1 and watchdog active on GPI 1.Watchdog condition is true.

Input Priority set to input 1 and watchdog active on GPI 1.Watchdog condition is false.



GPI self testTo check each GPI for proper functionality:

• connect each input with ground• switch on the device

The LEDs in the mid-section (ACTIVE PORT) indicate the result of the self test for a short moment at power up - for each connected input accordingly.

GPI 1 GPI 2

GPI 3 GPI 4

Result:• LED blinking = GPI contact is closed• LED OFF = GPI contact is not closed

The self test helps to trace a possible issue with the installation; i.e. if open contact is expected and the led is blinking (e.g. short-circuit) or if a closed contact is expected but the led is not blinking (e.g. broken link).






Monitoring via GPOFour GPOs enable reporting of the output state (active input and BLDS presence) by external equipment.Each GPO uses a low resistance (FET) switch to ground (GND). It can handle an external voltage source between 0 V and 24 V.A 5 V local voltage source can also be used for signalling purposes. Its output is current-limited to 200 mA.

Chapter 5: Working with BLDS™

Chapter 5: Working with BLDS™IntroductionThe Buffer Loop Detection System™ is used to detect silence or a corrupted input signal - e.g. caused by an application hang of the playout system (repeating buffers) or stuttered playback due to system overload. A BLDS generator creates a .wav fi le containing a low levelled signal which is inserted into the MADI stream.The artifi cial design of the BLDS signal enables reliable and inaudible switch-over within one sample.

BLDS GeneratorThe application is available for Windows® and macOS®.

1. Download the application at www.directout.eu

2. Unpack the zip archive and open the ‘BLDS_Generator.exe’ (Windows®) or ‘BLDS Generator.app’ (macOS®).



3. Defi ne sample rate and duration using the drop down menus.

4. Click ‘Generate’ to save the a 24 bit mono .wav fi le with the settings specifi ed.

NOTE

The BLDS signal is designed so that it is 16 bit safe and the level is below - 60 dBFS.



5. A ‘Save as’ dialogue appears. Store the fi le to your preferred location.

6. Import the .wav fi le into an audio session of your DAW. The BLDS signal needs to be present in one of the following audio channels: channel 8 / 16 / 24 / 32 / 40 / 48 / 56 / 64

NOTE

When duplicating the signal in the timeline carefully check that there are no gaps, crossfades or overlaps at the boundaries. This violates the BLDS condition resulting in possibly unwanted behaviour.

7. Adjust the priority setting to trigger the switch according to BLDS detection - see „Priority Setting“ on page 40.



Examples

Example 1 - BLDS, priority input 1

Both MADI inputs detect a valid input signal containing a BLDS signal. Input 1 is prioritized and active. If input 1 fails (BLDS error), input 2 is used. Once input 1 regains signal the switch will revert to input 1.

Example 2 - BLDS, no priority

Both MADI inputs detect a valid input signal containing a BLDS signal. Input 1 is prioritized and active. If input 1 fails (BLDS error), input 2 is used. Once input 1 regains signal the switch will revert to input 1.



Example 3 - Lock, no priority

Both MADI inputs detect a valid input signal without valid BLDS signal. No input is prioritized and input 2 is active. If input 2 fails (Loss of carrier), input 1 is used. Once input 2 regains signal the switch will remain at input 1.

Example 4 - Manual switching

Both MADI inputs detect a valid input signal without valid BLDS signal. No input is prioritized and input 2 is active. No automatic switch-over will occur at signal loss.
